Professional Window and Door Installation

A high-quality installation of premium windows and doors isn’t a job for beginners or DIY enthusiasts. For optimal performance, windows must be installed plumb, level, and square—perfectly “floating” in the rough opening. Improper load distribution can distort frames, leading to air and water infiltration and reduced energy efficiency. Most homeowners lack the specialized tools and expertise for a first-class installation.

It’s also crucial to install windows and doors without disturbing existing trim, ensuring a seamless, original look. At Sane Windows and Doors of St. Louis, our experienced installers are trained to get the job done right the first time.
